IMPROVEMENT IN CHURNS.

i Specilication forming part of Letters Patent No. `35,5410, dated June `10, 1862.

Tp all whom it may concern:

Be it known that 1l, JONATHAN PARKER,` a citizen of theUnited States of America, and a resident of Biddeford,in the county of York and State of Maine, have invented anImproved Ghurn; and I do hereby declare the same to be fully described in the following specification, and represented in the accompa` nying drawings, of which-- Figure 1 is a side elevation, and Fig.`2 a Fig. 3

dasher.` Fig. 5 is a transverse section through one of the dasher-openings. p

My inventionhas reference to the construc tion and operation of thedasher; and it-consists inmaking the dasher with orifices so inclined or arrnged within it as to producespiral currents in the cream while the dasher may be in the act of being either lifted upward or forced downward, In the drawings,A representsan upright tub provided withva cover, B, from the top of which `two posts `or standards, C C, are projected vertically. These standards pass through a cross header bar, D, which should be soapplied t-o themas to be capable of being moved The said bar D :is slotted lengthwise, as shownat'a, and arranged alongside of a" circular disk or wheel,

, E, which is affixed at its center to one end of J a horizontal shaft, F, which is `supported by land so as to be capable of revolving freely in another post, G, erected on the cover B. A`

y crank, H, is aflixed on the outer end of the shaft, and is so arranged with respectto a pin or stud, I, (which extends from the face of the i wheel Eend into the slot (1,) as to be about horizontal when suchpin is either )in its highest orlowest position. 4

also such as to cause the cross-head D to de- The arrangement is scend while the crank is being turned inthe lower halfofits circle of revolution. From the middleof the cross-head a dasher-rod, K, descends, passes through a hole in the cover, and at its lower end is affixed to `a Wooden disk `or dasher, L. The said dasher is madewith a series oflperl'orations, b `b b, which stand radially, although each is curvedlongitudinally. Each of these perforations is not made at right angles with the planefaces of the dasher, but is inclined thereto, and each of such perforal `tions is made somewhat wider at bottom than at top, in order that the cream during the downward stroke of the dasher may more readily pass into and through the opening.

The operation of the churn is as follows: While the crank is being turned a reciprocating, rectilinear, and vertical motion will beimparted to `the dasher, and the dasher will be forced downward while the crank is being moved through the lower halt' of the circle of its revolution. This will not only cause the weight or gravitating power of the dasher to assist in effecting its downward stroke, but will lcause the dasher to descend with a smart or quick dash or blow into the cream, and thereby facilitate the churning of it. Furthermore, owing to the arrangement of the perforations of the dasher, spiral currents will be produced I inthe cream during each ascent as well as during each descent of the dasher. Thus the cream, while the dasher may be working either way, will be put more orless-in rotation in a manner which, under the action of the dasher in other respects, will contribute materiallytoward effecting the rapid oxygenation of the cream or production of the butter.

I claim` The dasherv as made with perforations arranged at an inclination to its faces to operate in manner substantially as specified.
